Trigger TTL adjustments not showing up on strobe screen. TTL to ManualUpdated 24 days ago
When using an FJ Wireless trigger—such as the FJ-X3 M (S), FJ-X2 M, or the FJ80 (II and SE) in Host Mode—you can adjust TTL exposure compensation by ±3 stops (±5 stops on Fuji).
Total TTL Exposure Compensation Value
The FJ Wireless system offers a unique feature that allows TTL exposure compensation to be adjusted both on the trigger and on the flash unit itself. These two adjustments are combined to produce a total compensation value.
For example:
- If you set a +3 adjustment on your trigger, your strobe will output 3 stops more power.
- If you then add a +3 adjustment directly on the strobe/flash unit while the +3 on the trigger is still active, the result will be a total adjustment of +6 stops.
- Please note: When using TTL, the camera and host unit communicate with each other to automatically determine the optimal flash power for the scene. If your TTL photo appears too dark—even with the flash already firing at a high level (e.g., power level 6)—the maximum effective adjustment available may be limited. A +3 compensation might bring the unit to its maximum of power level 9 (full power).
In cases like this, if you attempt a combined +6 adjustment (e.g., +3 on the trigger and +3 on the flash), the system will only reflect a 3-stop increase in exposure—because the unit cannot exceed full power (level 9 or 1/1).
How to View TTL Exposure Compensation on Your Strobe
Westcott’s TTL to Manual feature allows you to see TTL exposure compensation values from the host unit, along with the actual power output used during the last TTL exposure. This is especially helpful for monitoring power levels, as lower output can lead to faster recycling times.
FJ400
- Press and hold the Menu button to enter Menu 6.
- Press the Select button until "OFF" next to M=TTL is highlighted.
- Press the Set button to change "OFF" to "ON."
- Press the Menu button once to exit the settings menu.
When in TTL mode, two new sets of numbers will appear in the lower-left corner of the screen above the sync icon:
- The top number (e.g., +0.0) is the TTL exposure compensation set by the host unit.
- The number below it (e.g., 1.0 to 9.0) shows the manual power equivalent of the previous TTL flash.
- The largest number on the screen represents the additional TTL adjustment made directly on the strobe.
FJ400 II and FJ800
- Touch and hold the Menu button to open the settings menu.
- Use the up and down arrows to navigate to the TTL to Manual setting.
- Tap to change the setting from "OFF" to "ON."
- Press OK to confirm.
- Press the Home button to exit the menu.
When in TTL mode, two new sets of numbers will appear on the left side of the screen under the TTL text:
- The top number (e.g., +0.0) indicates TTL compensation from the host unit.
- The number below it (e.g., 1.0 to 9.0) is the manual power equivalent from the last TTL exposure.
- The largest number shows the additional TTL adjustment applied directly on the strobe.
TTL to Manual with FJ200, FJ80iiM(S) and FJ-X3m
When enabling TTL to Manual mode on the FJ200 and FJ80, exposure compensation adjustments from the host unit will not be displayed. However, the manual equivalent of the previous TTL exposure will be shown.
FJ200
- Press the center control wheel to enter the settings menu.
- Rotate the wheel until "TTL→M" is selected.
- Press the control wheel and rotate it to change the setting to "On."
- Press the Return/Model button to exit the settings menu.
- Once enabled, an “M = 0.0” (or another value) will appear on the right side of the screen. The number under the new "M" icon represents the manual power output equivalent of the previous TTL exposure.
Once enabled, on the right side of the screen there will be an M = 0.0 (or a number). The number under the new "M" icon is the manual power out put equivalent of the previous TTL exposure.
FJ80iiM(S)
The TTL to M feature on the FJ80iiM(S) is only available in Host mode when attached to a camera. It displays the manual power equivalent of the previous TTL exposure.
- Press the Home button and select Host mode.
- Set Group A to TTL mode.
- Note: Group A not only controls other flashes assigned to that group but also controls the FJ80 itself.
- Take a photo.
- Touch the "A" of Group A once to select it.
- Touch and hold the "A" of Group A for about 4 seconds.
Group A will switch from TTL to Manual mode and automatically assign a manual power output that matches the previous TTL exposure.
FJ-X3M
The TTL to M feature is only available in group A
- Set Group A to TTL mode.
- Take a photo while Group A is in TTL.
- Press and hold the button on the left side of the trigger that corresponds to Group A.
Group A will switch from TTL to Manual mode and automatically assign a manual power output that matches the previous TTL exposure.
